We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they appear before them in a chain, because they produce multiple tokens at the same position. This commit adds two methods to the TokenFilterFactory interface. * `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and `CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`. * `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym list `Analyzer`. By default it returns `true`. Fixes #33609
